This is a talk given at the Redwood Center for Theoretical Neuroscience, UC Berkeley on March 1, 2007. Speaker is Hiroki Asari, Watson School of Biological Sciences, Cold Spring Harbor Laboratory. Abstract: A striking feature of many sensory processing problems is that there appear to be many more neurons engaged in the internal representations of the signal than in its transduction. For example, humans have about 30,000 cochlear neurons, but at least a thousand times as many neurons in the...

This is a talk given by Geoff Hinton, Dept. of Computer Science, University of Toronto, at the Redwood Center for Theoretical Neuroscience on November 27, 2007. Abstract. Neurons need to represent both the presence of a feature in the sensory input and the derivative of an error function with respect to the neural activity. I will describe a simple way in which they can represent both of these very different quantities at the same time and show that this representational scheme would make it...

This is last half of a talk given to the Statistics Dept. at UC-Berkeley by Liam Paninski of Columbia Univesrity on Oct 24, 2007. Unfortunately, the first half was not recorded because of technical problems. Sorry! Abstract: There are two basic problems in the statistical analysis of neural data. The ``encoding'' problem concerns how information is encoded in neural spike trains: can we predict the responses of a neuron (or population of neurons), given an arbitrary stimulus or observed motor...

Talk by Todd Horowitz of Harvard Medical School for the Redwood Center for Theoretical Neuroscience, on November 30, 2007 at UC-Berkeley. Abstract: Much of our current understanding of visual attention is built on experimental paradigms that can be characterized as either static or as a series of brief, discontinuous snapshots. However, in our everyday environment, objects around us move smoothly, or we move with respect to the environment. Recent research has tried to capture dynamic and...

This is a talk given at the Redwood Center for Theoretical Neuroscience, UC Berkeley on April 17, 2007. Speaker is Steve Waydo from the California Institute of Technology. Abstract: Neurons have been identified in the human medial temporal lobe (MTL) that display a strong selectivity for only a few stimuli (such as familiar individuals or landmark buildings) out of perhaps 100 presented to the test subject (Quian Quiroga et al., Nature 2005). While highly selective for a particular object or...

Since images are very non Gaussian, high dimensional, continuous signals, learning their distribution presents a tremendous computational challenge. Perhaps the most...
